SPECIFICATION forming part of Letters Patent No. 648,815, dated Ma 1, 1900.

Application filed August 9,1399. Serial n. 726,682. (No model.)

- of Spain, in the Islandof Trinidad, British \Vest Indies, have invented a new and Improved Air-Directing Device for Fans, of which the following is a full, clear, and exact description.

The object of my invention is to provide a device whereby the blast of air which is discharged from an electric fan or the like may be thrown in any desired direction, and especially whereby such blast may be directed at various angles upward and downward or to the right or left.

To accomplish the indicated results, I conw'uct a directing device, as shown in the acu nnpanying drawings, and as will be fully de- 'fil'lllod hereinafter.

The novel features will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters'of reference indicate corresponding parts in all the views.

Figure 1 is a face view of a fan provided with m'yimproved attachment. Fig.2 is a side elevation thereof with parts in section. Fig. 3 is'an enlarged detail view.

A designates the fan-casing, in which is journaled the fan proper, B, which may be of any approved construction. From the casing is supported by means of arms A, so as to extend in front of the fan B, a carrier 0, preferably of circular form, as shown, and provided with segmental slots 0, through which pass studs K, secured to a ring K, which is thus capable of alimited rotary sliding movement relativelyto the carrier 0. This ring contains a series, of slats D, hinged about parallel axes, which, as shown, are disposed horizontally and in the center of the cylindrical ring K, the pivots being indicated by the letter E.- Each of the slats at its outer end is pivotally connected to a link F, which is also pivotally connected -to the operatingbar G, fitted to slide up and down in guides H on the casing O and also capable of a slight inward and outward movement in said guides,

. as will be clear from the two positions of the bar G, indicated in Fig. 2 by full and dotted lines, respectively. The bar G is provided with operating finger-pieces G.

In order to secure the slats D in any posl tion after adjustment, I extend the axis or pivot of one of the said slats, preferably the central slat, as shown at E, and upon said projecting end Iarrange a clamping-nut l.

The operation of the device will be obvious.

- According to the angle at which the slats D maybe adjusted, the current of air produced by the rotation of the fan B will (when the ring K is so adjusted that the axes of the slatsarehorizontal) either be discharged horizontally, as usual, or will be deflected upward orsdowuward by a proper adjustment of the slats. By changing the adjustment of the ring Kin the carrier 0 the axes of the slats will be inclined, so as to deflect the air laterally to the leftor the right and at the same time upwardor downward, except when the ring is adjusted so as to place the axes of the slats in a verticalposition, in which case the deflection will be purely lateral. There will therefore be no necessity for moving the fan from its place, and my invention. therefore affords a very convenient means of regulating the action of the fan at any angle or in any direction.

Having thus, described .my invention, 1 claim as new and desireto secure by Letters Patent- 1 1. The combination with the fan and its casing, of a carrier rigidly connected with the easing, a support or frame adj ustably mounted on the carrier to turn about an axis approximately parallel to the fans axis of rotation, and slats adj ustably mounted on the said frame.

2. Thecombinat-ion of a fan, a cylindrical ring infront thereof, slats pivoted to the ring about horizontal axes, an operating-bar connected 'with all of the slats, and the clamping-nut on the pivot of one of the slats to lock them after-adjustment.

3. The combination with the fan and its casing, ofa carrier rigidly connected with the casing, a ring adjustably mounted on the carrier to turn about an axis approximately parallel to the fans axis of rotation, and slats ad j ustably mounted on said ring.
